36、 Status (refer to EN 13757-3) Conf. Word Configuration Word (refer to EN 13757-3) 4 General 4.1 Introduction The “meters” may communicate with “other” system components, for example mobile readout devices, stationary receivers, data collectors, multi-utility concentrators or system network component

37、s. Such devices are in this document named “Other Device”. For the meter side, it is assumed that the communication function will work without any operators intervention or need for battery replacement over the full lifetime of the radio part of the meter. Other components such as the mobile readout

38、 or stationary equipment may have a shorter battery lifetime or require an external power supply as dictated by the technical parameters and use. Several different modes of operation are defined for the communication with the meter. Many of the physical and link layer parameters of these different m

39、odes are identical, allowing the use of common hardware and software. However, due to the operational and technical requirements of these modes some parameters will differ. The name of a mode is specified by a letter and a number. The letter specifies a mode and the number specifies whether the mode

40、s supports unidirectional (=1) or bidirectional (=2) data transfer. a) “Stationary mode”, mode S is intended for unidirectional or bidirectional communications between the meter and a stationary or mobile device. A special transmit only sub-mode S1 is optimised for stationary battery operated device

41、s with a long header and the sub-mode S1-m is specialised for mobile receivers. b) “Frequent transmit mode”, mode T. In this mode, the meter transmits a very short frame (typically 3 ms to 8 ms) every few seconds, thus allowing walk-by and/or drive-by readout. Transmit only sub-mode T1. It is the mi

42、nimal transmission of a meter ID plus a readout value, which is sent periodically. The bidirectional sub-mode T2 transmits frequently a short frame containing at least its ID and then waits for a very short period after each transmission for the reception of a response. The reception of a response w

43、ill open a bidirectional communication channel. Alternatively, the initial frame contains the readout value as well, and the response is a reverse channel only used for special services. c) “Frequent receive mode”, mode R. In this mode only R2 is relevant, as R1 makes no sense. The meter listens eve

44、ry few seconds for the reception of a wakeup message from a mobile transceiver. After receiving such a wakeup, the device will prepare for a few seconds of communication dialog with the initiating transceiver. In this mode a “multi-channel receive mode” allows the simultaneous readout of several met

45、ers, each one operating on a different frequency channel. This mode is as well applicable to stationary Other Devices. d) “Compact Mode” mode C. This mode is similar to mode T but it allows for transmission of more data within the same energy budget and with the same duty cycle. It supports the sub-

46、modes C1 and C2 for unidirectional and bidirectional devices. It is suitable for walk-by and/or drive-by readout. The common reception of mode T and mode C frames with a single receiver is possible. e) “Narrowband VHF”, mode N. Optimised for narrowband operation in the 169 MHz frequency band, alloca

47、ted for meter reading and a few other services. Transmit only sub-modes N1a-f, and bidirectional sub-modes N2a-f. The range of sub-modes can be extended using repeaters. Sub-mode N2g is intended for, but not limited to, long range secondary communication using multi-hop repeaters. BS EN 13757-4:2013

48、EN 13757-4:2013 (E) 7 f) “Frequent receive and transmit mode”, mode F. Used in the 433 MHz frequency band for long range communications. In the bidirectional sub-modes F2-m, the meter listens every few seconds for the reception of a wake up message from a stationary or mobile transceiver. After rece

49、iving such a wake up message, the device prepares for a few seconds of communication dialog with the initiating transceiver. The bidirectional sub-mode F2 transmits a frame and waits for a short period for the reception of a response. The response will open for bidirectional communication. Meters or other communication devices may support one, multiple or all of the described modes. NOTE Additional modes, supporting repeating and routing of data, are specified in EN 13757-5.
